The L.A. County Department of Child Protective Services will be investigating an alleged brawl between Berry's ex Gabriel Aubry and her current boyfriend Olivier Martinez that left both men in the hospital!

Here's what a source said:

"Detectives from the LAPD formally contacted CPS after Gabe's arrest, because Nahla was present when the fight occurred. Nahla wasn't actually involved in the melee, and by all accounts, Halle whisked her out of the driveway as soon as the fight between Olivier and Gabe started. However, DCFS was contacted because there has been a history of allegations of physical abuse. Social workers will be interviewing Halle, Gabriel and Olivier about what happened on Thanksgiving. DCFS must ensure that Nahla's environment is safe."

Well, we're certainly glad that Nahla is safe and out of harm's way!

It seems a bit self destructive for Aubry to start a fight with Martinez after he just won a huge case to keep Berry from moving herself and Nahla out of the country.

Will this Thanksgiving melee come back to bite him right in the gobbler!?
